Many of the higher floors were more or less demolished–usually more. These would have been condos had ‘The Arcade’ project come to fruition. Now there are simply wide open floors punctuated only by pillars and meaningless hallways.

It is unclear when the ‘Superior Warehouse Company’ sign was put up, but it was likely around 1916-1917, when maps indicate it served as a dry goods warehouse, operated by Twohy-Eimon Mercantile Company. The Sivertson sign was likely added in the mid-1980s. In this image I tried to preserve the colors the bricks turn at sunset.

Every elevator has sets of these conveyor switches. Grain comes down through the top chute and the bottom chute rotates to move the flow onto various belts around the plant by gravity. The cross belt is another switch and the bridge belt brings the flow to the other half of the elevator.

The top floor of the nitrating house was full of switches and breakers for the operation below, each bearing a label and number. Nowadays everything is printed, but when INAAP was built, all these signs were painted by hand.
